Abstract
A semiconductor processing tool may include a processing tank. The semiconductor processing tool may include an arm arranged to hold a plurality of wafers over the processing tank such that wafers in the plurality of wafers are horizontally stacked over the processing tank. The semiconductor processing tool may include a fan arranged over the arm to permit an airflow to be provided across surfaces of the wafers in a vertical direction toward the processing tank. The semiconductor processing tool may include an exhaust system including at least one exhaust output and one or more exhaust pipe segments arranged substantially around the processing tank and connected to the at least one exhaust output. The one or more exhaust pipe segments may include a plurality of openings to receive exhaust air to be provided to the at least one exhaust output.
